Abstract: A self adjusting device interposed in the lever system of a friction clutch is disclosed. The device operatively connects a threaded adjusting ring and an axially shiftable actuating collar such that wear occurring in the friction surfaces of the clutch is automatically taken up during operation of the clutch. The self adjusting device includes a mounting bracket secured to the clutch cover. The mounting bracket includes a central U-shaped portion and a pair of flange portions, each extending outwardly from an end of the opposing sides of the U-shaped portion. A pin is retained in the opposing sides of the U-shaped portion of the mounting bracket. The pin rotatably carries a pair of hub members which effect the self adjustment of the clutch to compensate for wear of the friction surfaces. The U-shaped portion of the mounting bracket permits visual confirmation of correct installation and function of the self adjusting device.

Abstract: The feeding length in a sewing machine depends on the difference between the positions of the feeder when it rises above the stitch plate and when it sinks again. In previous devices the feeder is controlled by the angular position of a guide which is kept constant during the feeding phase. According to the invention the angular position of the guide can be re-adjusted during the feeding movement. At the moment when the feeder rises above the stitch plate the angular position determines a portion of the feeding length, while the angular position at the moment when the feeder sinks again determines the rest of the feeding length.

Abstract: Fume extractor for cooking equipment, which comprises a box 1 having an air extraction opening at the front, communicating with the interior of the box, the latter being connectable to a ventilation duct. The said opening comprises passages 14, 15 which are offset with respect to each other and define a curved air-circulating path for separating out particles entrained by the extracted air. The improvement consists in providing extra passages 17, 18 that are offset with respect to each other at the rear of the box, these passages having a smaller total flow cross section than the passages located at the front, so as to generate an additional weaker airflow along the wall 2 at the rear of the cooking equipment along the bottom 10 of the box, in order to prevent condensation on this wall and on the bottom respectively. <IMAGE>

Abstract: The invention belongs to the technical area of medical technics and devices for radiation treatment of cancer tumours. At radiation treatment of cancercells one is destroying not only the cancer tumours but also other parts of the body and therefore there exists problem with creating methods and devices that will only destroy the cancercells and not damage the rest of the body. As contribution to the solution of this problem is suggested this method and device. By physics experiment, awarded with Nobel prize in physics, is known that according to the laws of symmetry matter situated before a mirror gets a double of antimatter at the same distance from the mirror (which is symmetry axis) behind the mirror. The theory of the inventor is that if one by radiation destroys the antitumour (the double) which is of antimatter and is situated behind the mirror, one will because of the symmetry also destroy the cancer tumour which is of matter and is situated in the body at the exact distance from the mirror as its double. With the description is illustrated the idea of the invention; The patient 1, with the cancer tumour 2, is fixed at a table 3 before the mirror 5. At the same distance from the mirror 4 is the double of the cancer tumour 2A which is irradiated by the beam 5 after that the computer 6 has estimated the exact symmetric location for irradiation behind the mirror.

Abstract: The invention relates to a method of measuring the air- permeability of a material web 7, in particular a continuous press felt of a paper machine. At a nozzle 2 which is brought to bear against the web 7, a pressure drop is brought about across the web and thus an air stream which depends on the air-permeability. The pressure drop is regulated to a constant value and, at this constant value, the size of the air flow is measured as a measure of the air-permeability. The air flow is measured by a vortex measuring device 3 which is connected to the nozzle and emits an output signal with a frequency which is proportional to the speed of the air flow. The pressure drop is regulated by a precision regulator 4 which, on its secondary pressure side, is connected to the input side of the vortex measuring device 3 and which is adjusted to preferably at least 20 kPa. The nozzle 2, the vortex measuring device 3 and the precision regulator 4 are guided as a unit designed as a measuring head 1 across the web 7 to measure a transverse profile of the air-permeability of the web 7 by means of the output signal of the vortex measuring device 3. A compressed air source 9 separate from the measuring head 1 is connected to the primary pressure side of the precision regulator 4. <IMAGE>

Abstract: A cutter mounted on a boring head includes a shaft and a roller body rotatably mounted thereon The greasing of bearings disposed between the roller body and shaft is achieved through an axial bore formed in the shaft and into which a filling plug is inserted. Grease is pumped through the filling plug and into channels in which the bearings are disposed. The filling plug is then removed, leaving the bore essentially grease-free. To prevent the escape of grease from the passage during a cutting operation, while accommodating thermal expansion of the grease, a grease retainer plug is secured in the passage. The retainer plug forms a space which communicates with the bearings for receiving thermally expanding grease. If the volume of expanded grease exceeds the volume of that space, the grease passes through a pressure relief valve and displaces a cover of the valve to create another space of gradually expanding volume for receiving the grease.

Abstract: Method for adapting the amount of messages with a number of various identities transferred between a transmitter (1) and a receiver (2). The transfer is accomplished in such a way that no essential information is lost even if the message rate (d1) from the transmitter exceeds the possible transfer rate (d2). According to the invention a data area is created in which each message with a certain identity is stored while awaiting to be transferred. When a new message with the same identity as an earlier stored message is supplied to the data area, the new message replaces the earlier stored message. The messages stored in the data area are scanned and are transferred to the receiver at a rate which is adapted to the rate possible for the transfer. <IMAGE>

The wavelength cross-connectors are used to connect together different nodes in the coupling system and are comprised of two different passive components: optical circulators and fiber gratings. A 2x2 wavelength cross-connector is formed by two circulators that are connected together through the medium of a fiber grating connected to the intermediate ports of the circulators. To construct a 4x4 wavelength cross-connector, two 2x2 wavelength cross-connectors are used, wherein the outputs of the 2x2 wavelength cross-connectors are connected together in pairs by means of circulator-pairs and a fiber grating. The fiber gratings reflect certain of the wavelength channels in the input signals delivered to the inputs and transmit remaining wavelength channels, thereby enabling each node to communicate with each other node. This enables wavelength cross-connectors having N inputs and N outputs to be built-up.

In the beam path of the electromagnetic radiation, polarization of the electromagnetic radiation, polarization modulation of the polarization direction on the electromagnetic radiation by alternately changing it, and polarization of the electromagnetic radiation take place in sequence. At least on of these steps is performed at the target reflector. Checking of the detected reflector is carried out by testing if the received radiation changes at the same rate as the modulation of the polarization direction. Only targets are accepted which give different signal strengths at said rate for the received radiation.
